TORONTO — DeMar DeRozan and Kyle Lowry both struggled with their shooting, but it didn't matter. Toronto's two top stars found other ways to contribute, and the rest of the roster added plenty of punch in the Raptors' season-opening victory. DeRozan had 15 points and set career-highs with 11 rebounds and six steals, Lowry added 11 points and 10 assists, and the Raptors opened their defense of the Atlantic Division title with a 109-102 victory over the Atlanta Hawks on Wednesday night.
